Japanese Utility Model Publication No. 59-131346.
[0005]
[Problems to be solved by the invention]
Since the above-mentioned slide rail has a relatively short length in the front and rear, there is no particular problem, but when this slide rail is set relatively long to overlap the seat cushion of the front seat and the seat cushion of the rear seat, When the rear seat occupant seated on the rear seat spreads his legs and moves upward, the rear seat occupant's feet may come into contact with the rail from below the slide rail, and the slide rail may be deformed.
[0006]
The above-mentioned slide rail is an important part that slides and guides the anchor under the seat belt for restraining the front seat occupant in the front-rear direction of the vehicle, and should not be originally deformed.
[0007]
Therefore, the present invention is a floor mat arranged from the floor to the upper surface of the side sill inner, and in order to close the gap between the slide rail and the floor, the side sill side surface portion between the front seat and the rear seat is provided. By bulging the floor mat toward the vehicle interior side, it is possible to prevent deformation of the slide rail due to the foot of the rear seat passenger coming into contact with the slide rail from below the slide rail. It is an object of the present invention to provide an automobile interior material arrangement structure in which an occupant's foot is inserted in between and a slide rail is not deformed or occupant is tripped .
[0008]
[Means for Solving the Problems]
The vehicle interior material arrangement structure according to the present invention is a vehicle interior material in which a slide rail is provided along a side sill on the side of a vehicle body to guide an anchor of a seat belt for a front seat seated occupant so as to be movable in the longitudinal direction of the vehicle. The seat bracket for mounting the front seat is fixed to the side sill inner so as to protrude toward the passenger compartment, and the slide rail is attached to the side sill inner near the upper side of the seat bracket. The floor mat is further installed from the floor to the side sill inner side and the top side of the side sill inner so as to cover the seat bracket, and the floor mat on the side sill side surface between the front seat and the rear seat bulges toward the vehicle interior side. floor by forming the bulging portion, to cover the bulging part and the seat bracket The gap between the slide rail and the floor is characterized Rukoto closed by Tsu and.
The seat belt having the above configuration may be set for restraining the front seat occupant.
[0009]
According to the above configuration, the floor mat on the side sill side surface between the front seat and the rear seat is inflated by inflating the floor mat toward the vehicle interior so as to close the gap between the slide rail and the floor. Since the protruding portion is formed, the bulging portion can prevent the foot of the rear seat occupant from being positioned below the slide rail.
[0010]
As a result, it is possible to prevent the deformation of the slide rail caused by the foot of the rear seat occupant coming into contact or pressure contact with the rail from below the slide rail.
[0011]
In one embodiment of the present invention, a hollow member fixed to the side surface of the side sill inner is provided inside the bulging portion.
According to the said structure, a bulging part can be formed in low weight and cheaply with the above-mentioned hollow member.
[0012]
In one embodiment of the present invention, the hollow member is spaced apart from the floor surface by a predetermined distance, and a predetermined portion of the hollow member is fastened to the side surface of the side sill inner.
According to the said structure, the above-mentioned bulging part can be formed reliably, ensuring the miniaturization of a hollow member and a fastening structure.
[0013]
In one embodiment of the present invention, a collision sensor is provided inside the hollow member.
You may set the collision sensor of the said structure to a side collision sensor, ie, a side collision sensor.
According to the above configuration, it is possible to dispose the collision sensor having excellent protection performance by effectively using the dead space inside the bulging portion.
[0014]
In one embodiment of the present invention, a front door includes a front door that is supported by the vehicle body so as to be opened and closed, and a rear portion that is supported by the vehicle body so that the vehicle can be opened and closed, and the seat belt is provided on the rear door. is there.
[0015]
According to the above configuration, in a vehicle having a front door and a rear door having a double door structure, when the rear door is opened, the anchor of the seat belt moves rearward in the front-rear direction of the vehicle along the slide rail. Sex can be secured.
[0016]
The automobile interior material arrangement structure according to the present invention also includes an automobile interior material in which a slide rail is provided along a side sill on the side of the vehicle body to guide the anchor of the front seat seated occupant seat belt so as to be movable in the longitudinal direction of the vehicle. The seat bracket for mounting the front seat is fixed to the side sill inner, and the slide rail is attached to the side sill inner near the upper side of the seat bracket, and the side surface of the side sill inner from the floor. And a floor mat is arranged over the upper surface of the side sill inner, and the floor mat on the side surface of the side sill between the front seat and the rear seat is bulged toward the interior of the vehicle to form a bulged portion. The gap between the slide rail and the floor is closed, and the seat bracket is swollen. The slide rail is disposed so as to be positioned a predetermined distance above the bulging portion above the bulging portion, and a hollow member fixed to the side surface of the side sill inner is provided inside the bulging portion. In addition, a collision sensor is provided inside the hollow member.
[0017]
According to the above configuration, the floor mat on the side sill side surface between the front seat and the rear seat is inflated by inflating the floor mat toward the vehicle interior so as to close the gap between the slide rail and the floor. Since the protruding portion is formed, the bulging portion can prevent the foot of the rear seat occupant from being positioned below the slide rail .
[0018]
As a result, it is possible to prevent the deformation of the slide rail caused by the foot of the rear seat occupant coming into contact or pressure contact with the rail from below the slide rail. Further, by having the hollow member and the collision sensor, the bulging portion can be formed at a low weight and at a low cost, and the space inside the bulging portion can be used effectively.
